To aZZwhom it may concern.-

Be it known that I, HENRY C. MILLER, of

"Milwaukee, in the county of Milwaukee and State of Nisoonsin, haveinvented a new and useful Improvement in Backs for Temporary Binders, ofwhich the following is a description, reference being had to theaccompanying drawings, which are a part of this specification.

My invention has relation to improvements in hacks for temporary bindersor other books having movable cover-sections.

The object of the invention is to provide,

in a temporary binder or other book having movable cover-sections, an'improved construction of rounded back, whereby the book when opened isadapted to be readily turned on said rounded back to thereby permit theleaves to he turneds'c as to lie flat or in a suh-v stantiallyhorizontal plane inorder to facilitate writing thereon.

' Vifith the above primary object in view the invention consists of thedevices and parts or their equivalents, as hereinafter more fullysetforth.

in the accompanying drawings, Figure 1 is a perspective view of abinder, showing one form of my invention; and Figs. 2, 3, 4., and 5aresimilar views of fragments of tempo rary binders, showing,respectively, different modifications of the invention.

Throughout all the figures of the drawings the numeral 6 indicates oneof the cover-sections, provided with a rear binding-piece 7, forming apart thereof, and the numeral 8 the other cover-section, provided with arear binding-piece 9, forming a part thereof.

In each figure of the drawings also the rear binding-piece 7 is shown asprovided at its rear edge with a projecting flange 10 at right anglesthereto and the binding-piece 9 with a similar flange, the said flangesoverlapping and capable of sliding one within the other. The flange ofthe binding-piece 9 (shown in Fig. 1) is indicated by the numeral 11,and the corresponding flange in all the other figures of the drawings bythe numeral 11.

While I have shown and specifically described the fianges 10, 11, or 11,yet I do not wish to be understood as limiting myself thereto, inasmuchas it is possible in one of the forms shown to omit one of said flanges,while in the other forms one flange may be omitted, or both flanges, asdesired.

It will be understood that in the manufacture of the most common form oftemporary hinders the binding-pieces 7 and 9 are formed of strips ofmetal covered by suitable material, such as leather, and theflanges" 10,11, or 11 may be formed of the same strips of metal,

the flanges being produced by bending said metal at right angles, theflanges so produced being. ordinarily also covered with suitablematerial, such as leather. strips, however, I have not deemed necessaryto show herein, as they are well known in this art. Besides it is not myintention to limit myself to the use of such metallic strips. 1'

therefore nierelymake. mentionof the same herein in order to renderclear the fact that I prefer to use such strips in the manufacture ofthe binders.

" In the form of construction shown in Fig. 1

These metallic the outer flange 11 is of rounded contour and is shown asa continuation of the bindingstrip 9. I instance makes the roundedcontour of the back. In all the other figures of the drawings thecorresponding flange 11 is devoid of this rounded contour, and saidrounded contour is formed on other parts.

Referring to Fig. 2, 12 indicates a strip or block having an inner flatside and a rounded outer side. The inner flat side is secured to theface of the flange 11 in any desirable manneras, for instance, it may beglued thereto or attached by screws or equivalents.

The flange 11 itself therefore in this By thus providinga separate stripor block 12 an advantage is secured, inasmuch as when said part becomesworn it may be readily removed and another similar block substitutedtherefor.

In the form illustrated in Fig. 3 instead of I employing a single continuous block similar to 12, applied to the outer flange 11, Ishow assecured to said flange separate small blocks 13 13, having rounded outersides and inner fiat faces,which faces fit against the flange 11. Theseblocks may also be removable, so. that in case of wear others may besubstituted .tion whereinthe rounded contour is preserved, no matter towhat extent the coversections may be spread apart by the insertion ofthe additional leaves. The rounded contour is thereby not onlypreserved, but the appearance also enhanced.

Referring particularly to Fig. 4, the nu meral 1-1 indicates asupplemental rounded strip, which is shown as hinged at 15 to the loweredge of the flange 11, said hinge being constfucted in any desirablemanner, but prefe rably formed by means of the leather or other coveringused in the binder. A similar curved strip 16 is hinged at 17 to theupper edge of the flange 10. This hinge is also shown as formed by theleather or other covering of the binder. The curved strip 16 fitsagainst the inner side of the strip 14L. 13y thisconstruction it will beobvious that as the cover-sections are adjusted fartherapart or closertogether by the insertion or removal of leaves, as the case may be, thecurved hinged strips or back-sections will automatically conform to theadjustment, owing. to the free turning thereof on their hinges, andthereby pheserve the rounded contour. I pro vide ore the sections-saysection 14-with inwar lyektending pins 18 18, which fit in elongatedslots 19 19 in the other back-section, the innerends of the pins beingprovided with heads (not shown) which bear against the inner side or thecurved back-section 16, thereby preventing the two back-sections fromseparating.

In the form shown in Fig. 5 the flange 11 has hinged to its lower edgeby ordinary hingejoint connections 20 20 the rounded or curved tubulararms 21 21. Into these tubular arms pass other arms 22 22, which areconnected to the flange 10 by means of ordinary hinge-joint connections23 It is obvious that the parts can be reversed without departing frommy invention-that is to say, the tubular. arms 21 may be connected tothe flange 10 and the arms 22 to the flange 11. It is evi dent that thisconstruction will effect the same function as the construction shown inFig. 4, the telescoping arms 21 and turn ing upon their hinges, so as toconform to the increased-or decreased thickness of the book, and thetelescoping feature preventing the arms from separating.

As above stated, in one of the forms of construction shown only one ofthe flanges 10 or 11 is absolutely necessary, while in all the otherforms only,one of said flanges may be employed, or both may be omitted.For instance, in the Fig. 1 form the flange 10 could be entirelyomitted, and also, if desired, the flange 11 instead of extendmg fromthe hinding-strip 9 could extend from the bindingstrip 7. In Fig. 2 alsoeither one of the flanges 10 or 11' couldbe omitted and the block 1.2secured to the single remaining flange, or, again, in said Fig. 2 form.both flanges could be omitted and the block 12 secured directly to therear edge of either of the binding-strips 7 or 9. The same is true inregard to the Fig. 3 form that is to say, the blocks 13 13 could besecured to one of the flanges 10 or 11 and the other flange omitted, orboth flanges could be omitted and the blocks secured to the rear edge ofeither of the binding-strips 7 or 0.

In the constructions shown in Figs. 4 and 5 it is obvious that one orboth flanges could also be omitted. In case both flanges are omitted thehinged arms, respectively, would then be secured to the rear edges ofthe binding-strips 7 and 9.

From the foregoing description'it'is thought that the advantages of myinvention will be readily understood. in a temporary hinder or otherbook having movable cover-sections it is desirable when entries are madetherein that the leaves may be turned so as to lie flat, in order toenable entries to be readily made. The several constructions illustratedin the accompanying drawings render it possible to accomplish thisobject in a simple manner, and at the same time a-much neaterconstruction is provided than where a perfectly flat back is employed.

lVhat I claim as my invention is-- 1. In a back for a binder, or otherbook, the combination, with movable cover-sections, of curvedoverlapping back-sections, the convexity of the curves being outermost,

and said back-sections hinged, respectively,

to the cover-sections and slidingly fitted together, whereby as thecover-sections are moved closer together or farther apart, a continuousrounded contour of the back is preserved.

2. In a back for a binder, or other book, the combination, of movablecover-sections, curved overlapping back-sections, the convexity of thecurves being outermost, and said back-sections hinged, respectively, tothe cover-sections and slidingly fitted together, whereby, as thecover-sections are, moved closer together or'rartner apart, a continuousrounded contour to the back is preserved, and means for preventing theseparation of the bacleseetions.
